I'm not sure I understand, but if you want to add the Wegpunkt to the report you just have to click on the icon ("klicke auf die Karte" as it's written on top of the waypoint selection window not drag and drop).

As I think that adding an icon is not necessarily as straightforward as it might appear to those already in the know, and as a help for those who might encounter the same stumbling block, let me go a little more into detail:

“Wegpunkt” in Hikr-speak is not necessarily limited to a point that one has passed on his or her tour. It might sometimes as well be used in a broader sense to denote just any location. For which “Ort” normally would be a more appropriate term in german.

So in case you want to put an icon onto one of your photographs first click on “Einen Ort hinzufügen”. Then a new box will appear below where you may type in the name of the “Ort” in question. In case it is already existing in the Hikr database just click on it.
If it is not, you may wonder what to do next. The answer is to click on the symbol for Magnifying glass at the right side of the box..
Then a new window will pop up with the headline “Wegpunkte”(sic!).Most probably you will now have to click on “Neuer Punkt” and thereafter type in the details of it. When this is “fertig” the pop-up window will close and you will return to the main window.

In the newly added box entitled “Auf dem Bild” the name of your Wegpunkt or Ort will appear with an icon in front of it. T h i s one here is now the correct icon to drag..

Do not be mislead at an earlier stage (as you easily might be, I speak from own experience) and try to drag the icon one box higher where it says
